[SCSI] ibmvscsi: prevent scsi commands being sent in invalid state
There is a window where we can be re-enabling an adapter, but
still allow SCSI commands to be sent to the target. This fix
sets our window (request_limit) to -1 as soon as we know the
adapter is being reenabled, and closes a very teeny tiny
window where we could set the window back to 1 before we
grab a lock.
